Fall was full of firsts for T by Alexander Wang, which continues to expand to offer a more comprehensive wardrobe. Believe it or not, T has never done full-on leather pants before, and the downtown staple made its debut this season (although ringing up at $995, these might be more than you bargained for from the lower-priced line). Another introduction was print: a muted, wallpaperlike one meant to mimic jacquard, which appeared on soft button-ups and signature maxi slipdresses. One thing you can always expect from T is fabric innovation. The raw-edged, scuba-esque neoprene here (echoing the main collection's recent sporty theme) looked fresh on pleated short skirts and racer-neck dresses that were layered with cropped, chunky knits. And speaking of knits, we can't get enough of Wang's must-have take on the oversize, borrowed-from-the-boyfriend topper, which looks substantial but is actually sweater-weight—perfect for freakishly warm winter days like those we've been having recently.
